Adjusting the radius of sunburst plot before overlaying

When I overlay two sunburst plots, I found one plot completely covers the other one since they have the same size.
So I’d like to know if there’s any good way to adjust radius or size of the sunburst plot. Then I could enlarge one plot and put the other plot onto it.

In detail, I wanted to compare the outer-most portions of the two sunburst plots (see figure below). My trial was overlaying them by fig1.add_trace(fig2.data[0]). And end-up finding there’s no way to adjust the size of each trace separately. Resizing figure size seems to have no effect as two traces belongs to the same figure.

Sorry for the poor figure but I believe you got my idea
